The 2.5kV rms galvanic isolation separates the logic side (VCC1 = 3.3V\/5V) from the bus side (VCC2 = 5V), breaking ground loops and providing protection against high common-mode voltages. The half-duplex transceiver supports data rates up to 20Mbps with full failsafe receiver operation. The driver outputs feature +\/-15kV HBM ESD protection, and the hot-swap input structure prevents data glitching during hot-plug events. The REEL7 suffix indicates tape and reel packaging with 1000 units per reel.","working_principle":"The ADM2484EBRWZ-REEL7 combines digital isolation with RS-485 transceiver functionality. (1) The digital isolator section uses iCoupler technology with on-chip transformers to transfer three logic signals (DI, DE, RE) across the isolation barrier. (2) The RS-485 transceiver section on the bus side converts single-ended logic signals to differential signals on the A and B bus pins for transmission, and converts received differential signals back to single-ended logic on the RO pin. The driver enable (DE) and receiver enable (RE) control the direction for half-duplex operation. (3) The full failsafe receiver ensures the output is logic high when the bus is open, shorted, or idle, preventing false data from noise.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VCC1<\/td><td>Logic-side supply (3.3V or 5V)<\/td><\/tr><tr><td>2<\/td><td>RO<\/td><td>Receiver output<\/td><\/tr><tr><td>3<\/td><td>RE<\/td><td>Receiver enable (active low)<\/td><\/tr><tr><td>4<\/td><td>DE<\/td><td>Driver enable (active high)<\/td><\/tr><tr><td>5<\/td><td>DI<\/td><td>Driver data input<\/td><\/tr><tr><td>6<\/td><td>GND1<\/td><td>Logic-side ground<\/td><\/tr><tr><td>9<\/td><td>GND2<\/td><td>Bus-side ground<\/td><\/tr><tr><td>10<\/td><td>A<\/td><td>Non-inverting bus pin<\/td><\/tr><tr><td>11<\/td><td>B<\/td><td>Inverting bus pin<\/td><\/tr><tr><td>12<\/td><td>VCC2<\/td><td>Bus-side supply (5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Isolated Modbus RTU communication between PLC and remote I\/O modules<\/li><li>Profibus DP fieldbus node with galvanic isolation from bus<\/li><li>Motor drive communication interface with ground loop prevention<\/li><li>Building automation BACnet MS\/TP network isolated transceiver<\/li><li>Isolated USB-to-RS485 converter for industrial programming<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>ADM2484EBRWZ<\/td><td>Analog Devices<\/td><td>Tube packaging<\/td><\/tr><tr><td>ADM2483EBRWZ<\/td><td>Analog Devices<\/td><td>Full-duplex version<\/td><\/tr><tr><td>ADM2587EBRWZ<\/td><td>Analog Devices<\/td><td>Isolated with integrated DC-DC<\/td><\/tr><tr><td>ISO3086DW<\/td><td>TI<\/td><td>Isolated RS-485, 20Mbps<\/td><\/tr><tr><td>SIL9010<\/td><td>Silicon Labs<\/td><td>Isolated RS-485, 1Mbps<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7481","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7481"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7481\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7481"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7481"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7481"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7481"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
